Increased energy efficiency helps the world energy balance and productive conservation is no less an energy alternative than the energ

y sources. Substantial energy savings began to occur in the United States in the 1970s when the federal government imposed a nationwide automobile efficiency standard and offered tax deductions for insulating houses and installing solar energy panels.

Some obstacles stand in the way of conserving energy. It requires hundreds of millions of people to do routine things such as turning off lights and keeping tires properly inflated. Also, the price of energy is very high. Low energy prices make it difficult to convince people to invest in energy efficiency. Over time, improvements in energy efficiency more than pay for themselves. They also, however, require large capital investments, which are not attractive when energy prices are low.

High-energy prices in the 1970s started efficient energy use in constructing buildings and houses. Techniques to save energy include designing buildings to use passive solar heat, using computers to monitor and regulate the use
